Revert "Flatten Requests interface into Connection"next

This reverts commit 28c6e0d0454efc54f9a24da631eb75e6fcf925ba. I decided against it: > This might actually not be such a great idea. EnsureChannel and > CreateChannel should clearly be core, and RequestableChannelClasses > (aka TP_CONNECTION_FEATURE_CAPABILITIES) can reasonably be core > while connected, but Channels (and its change-notification, > NewChannel(s) and ChannelClosed) are sufficiently special-purpose > that I think only the AM and regression tests should be using it. > Having the Channels and their immutable properties in the GetAll > result seems non-optimal.
